Trading millet and sorghum genetic resources women vendors in the village fairs of San and Souentza, Mali:

"In Mali, liberalization of seed markets for sorghum and millet, the staple food crops, has not advanced at the same rate or with the same measurable success as liberalization of grain markets. Most seed of these crops is uncertified and continues to be supplied to farmers by farmers, according to clan and ethno-linguistic group. After poor harvests or when replanting after a dry spell, farmers rely on local markets for grain as sources of seed. This paper summarizes the findings of a vendor survey conducted in two marketsheds during weekly fairs. No certified seed is sold. Almost all vendors are women who are also farmers. Variety integrity is maintained particularly for millet seed in the marketshed of the Sahelian zone, where the range of variety adaptation is very limited. Grain that is suitable for seed is brought to market directly from granaries. Varieties are identified by their provenance. Socially prescribed behavior is apparent in price-fixing, price discounts, procurement practices, and the spatial organization of vendors. Preliminary hypotheses are tested with a simple regression. Marketshed, which is highly correlated with the ethnic composition of the population, agro-ecology, market infrastructure and crop sold, has a dominant impact on quantities sold. Quantities sold do not respond to expected prices. Greater specialization of the vendor in trade as compared to farming, younger age, and additional years in school positively influence amounts sold. A better comprehension of this type of trade could contribute to policies that improve the access of poor farmers to valuable crop genetic resources, enhancing their seed security and productivity." from Author's AbstractAgricultural development, Informal sector, Seed markets, Traders, Landraces, Millet, Sorghum, Women, Biodiversity,

An exploratory analysis of the regionalization policy for the recruitment of health workers in Burkina Faso

BACKGROUND: Health personnel retention in remote areas is a key health systems issue wordwide. To deal with this issue, since 2002 the government of Burkina Faso has implemented a staff retention policy, the regionalized health personnel recruitment policy, aimed at front-line workers such as nurses, midwives, and birth attendants. This study aimed to describe the policy’s development, formulation, and implementation process for the regionalization of health worker recruitment in Burkina Faso. METHODS: We conducted a qualitative study. The unit of analysis is a single case study with several levels of analysis. This study was conducted in three remote areas in Burkina Faso for the implementation portion, and at the central level for the development portion. Indepth interviews were conducted with Ministry of Health officials in charge of human resources, regional directors, regional human resource managers, district chief medical officers, and health workers at primary health centres. In total, 46 indepth interviews were conducted (February 3 - March 16, 2011). RESULTS: Development The idea for this policy emerged after finding a highly uneven distribution of health personnel across urban and rural areas, the availability of a large number of health officers in the labour market, and the opportunity given to the Ministry of Health by the government to recruit personnel through a specific budget allocation. Formulation The formulation consisted of a call for job applications from the Ministry of Health, which indicates the number of available posts by region. The respondents interviewed unanimously acknowledged the lack of documents governing the status of this new personnel category. Implementation During the initial years of implementation (2002-2003), this policy was limited to recruiting health workers for the regions with no possibility of transfer. The possibility of job-for-job exchange was then approved for a certain time, then cancelled. Starting in 2005, a departure condition was added. Now, regionalized health workers can leave the regions after undergoing a competitive selection process. CONCLUSION: The policy was characterized by the absence of written directives and by targeting only one category of personnel. Moreover, there was no associated incentive—financial or otherwise—which poses the question of long-term viability

The evolving SARS-CoV-2 epidemic in Africa: Insights from rapidly expanding genomic surveillance

INTRODUCTION Investment in Africa over the past year with regard to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) sequencing has led to a massive increase in the number of sequences, which, to date, exceeds 100,000 sequences generated to track the pandemic on the continent. These sequences have profoundly affected how public health officials in Africa have navigated the COVID-19 pandemic. RATIONALE We demonstrate how the first 100,000 SARS-CoV-2 sequences from Africa have helped monitor the epidemic on the continent, how genomic surveillance expanded over the course of the pandemic, and how we adapted our sequencing methods to deal with an evolving virus. Finally, we also examine how viral lineages have spread across the continent in a phylogeographic framework to gain insights into the underlying temporal and spatial transmission dynamics for several variants of concern (VOCs). RESULTS Our results indicate that the number of countries in Africa that can sequence the virus within their own borders is growing and that this is coupled with a shorter turnaround time from the time of sampling to sequence submission. Ongoing evolution necessitated the continual updating of primer sets, and, as a result, eight primer sets were designed in tandem with viral evolution and used to ensure effective sequencing of the virus. The pandemic unfolded through multiple waves of infection that were each driven by distinct genetic lineages, with B.1-like ancestral strains associated with the first pandemic wave of infections in 2020. Successive waves on the continent were fueled by different VOCs, with Alpha and Beta cocirculating in distinct spatial patterns during the second wave and Delta and Omicron affecting the whole continent during the third and fourth waves, respectively. Phylogeographic reconstruction points toward distinct differences in viral importation and exportation patterns associated with the Alpha, Beta, Delta, and Omicron variants and subvariants, when considering both Africa versus the rest of the world and viral dissemination within the continent. Our epidemiological and phylogenetic inferences therefore underscore the heterogeneous nature of the pandemic on the continent and highlight key insights and challenges, for instance, recognizing the limitations of low testing proportions. We also highlight the early warning capacity that genomic surveillance in Africa has had for the rest of the world with the detection of new lineages and variants, the most recent being the characterization of various Omicron subvariants. CONCLUSION Sustained investment for diagnostics and genomic surveillance in Africa is needed as the virus continues to evolve. This is important not only to help combat SARS-CoV-2 on the continent but also because it can be used as a platform to help address the many emerging and reemerging infectious disease threats in Africa. In particular, capacity building for local sequencing within countries or within the continent should be prioritized because this is generally associated with shorter turnaround times, providing the most benefit to local public health authorities tasked with pandemic response and mitigation and allowing for the fastest reaction to localized outbreaks. These investments are crucial for pandemic preparedness and response and will serve the health of the continent well into the 21st century
